Top German retailer UW-Fotopartner is insolvent and filed for bankrupcy in january 15. They offered brands like Nauticam, iDivesite, Fisheye/FIX, etc.
UW-Fotopartner is famous for basically moving their entire shop to the floor of the Boot show in Düsseldorf each year.
For Boot 2018 part of the UW-Fotopartner stand has been filled up with swiss retailer Fantic, which however will not sell anything at the show. And since all goods from Fantic is shipped from Switzerland it's more cumbersome for shoppers in neighboring EU countries.
